Research on heart attacks and their treatment. Covers care for older patients, cardiac rehabilitation, rapid testing, and updated diagnostic definitions.
An international study reveals that up to a third of patients with severe heart attacks may not receive reperfusion therapy, despite its well-known benefits. The study highlights variation in treatment practices and identifies factors contributing to underuse, including patient age, medical history, and geographical location.
A meta-analysis of six trials involving 31,400 patients found that anti-clotting drugs reduced death risk by 9% overall, but men showed a significant 19% reduction, while women saw no benefit. The treatment effect was greatest in high-risk patients.
Researchers found that regular use of aspirin cuts coronary heart disease risk by 28% in people at heightened risk. Doctors should discuss pros and cons with patients to determine individualized decision, considering age, habits, and medical histories.
The USPSTF recommends discussing aspirin therapy with adult patients at increased risk of coronary heart disease, such as those with unfavorable cholesterol levels, smoking, or hypertension. Aspirin may help prevent heart attacks in these individuals, but its benefits and harms should be carefully weighed.
A new study strengthens evidence that aspirin prevents heart attacks and strokes in patients with high-risk conditions like angina and diabetes. Researchers estimate an extra 40,000 lives could be saved annually if more people with these conditions receive aspirin.
Researchers found that embryonic stem cells can survive in damaged heart muscle and improve cardiac function. The study demonstrated significant reduction of MI damage and improvement in left ventricular function, suggesting a potential future treatment option for congestive heart failure.
A recent study found that blood pressure-lowering drugs have varying effects on heart attacks and strokes. Researchers argue that existing testing methods may not accurately reflect a drug's true effectiveness.
Researchers found that apolipoprotein B and A-I were strongly linked to increased risk of fatal heart attack in both men and women. Higher concentrations of ApoA-I had a protective effect, suggesting apolipoproteins may be valuable for diagnosis and treatment.
A study found that nontechnical aspects of hospital care, such as emotional support and coordination of care, are crucial for heart attack patients' long-term health. Patients with worse hospital experiences reported poorer health at 12 months, but those with good follow-up care from outpatient providers showed similar health outcomes.
A UCSF study suggests that with effective programs, including anti-tobacco media campaigns and community-based efforts, the US can reduce its adult smoking rate from 23-26% to 15% by 2010. This goal is within reach due to successful large-scale tobacco control initiatives in states like California.
A US study of 2,481 heart disease patients found that treatment did not lower mortality rates despite reducing depression and boosting social support. Researchers hope to analyze data further to understand why the treatment failed to benefit patients.
A new Stanford University study analyzed the costs and benefits of two treatments: implantable cardioverter defibrillators (ICDs) and the drug amiodarone. ICDs were found to be the most effective in preventing sudden cardiac death, but also came with the highest costs. Amiodarone produced intermediate benefits and costs.
Researchers found that troponin levels can accurately predict future heart attack risk, even when traditional measures are negative. The study suggests using troponin as a reliable indicator of cardiac cell damage, rather than creatine kinase-MB, to detect high-risk patients.
A new protein test has been developed to improve heart attack detection, particularly in cases of non-ST segment elevation heart attack. The test shows significant predictive value and could lead to a doubling of identified patients with mild heart attacks.
The study found that prehospital administration of the clot-dissolving drug reteplase decreased treatment time by more than 30 minutes at hospitals with average transport times and in-hospital treatment times. The savings exceeded 45 minutes at slower treatment time hospitals, highlighting the potential to improve patient outcomes.

Researchers also discovered that inhaled insulin shows promise for treating type 2 diabetes, improving blood sugar control without serious side effects.
A new study suggests that scenario-based counseling can help patients seek hospital care sooner after a heart attack, potentially improving survival rates. The intervention teaches patients to recognize the diversity of symptoms and address emotional responses to a heart attack threat.
A new study led by UCSF researchers suggests that prescribing beta-blockers to most people who have had heart attacks could save seven times more years of life than mammography screening over 20 years. The study projects 4,000 lives saved and 3,500 averted heart attacks at a reasonable cost.
A Yale study of over 51,000 participants found that taking aspirin daily reduces the risk of a first heart attack by 32%. However, it did not significantly reduce overall stroke or cardiovascular death rates, and may increase the risk of hemorrhagic stroke.
The U-M program has been shown to boost the use of key therapies in hospitals, with 98% of eligible patients receiving clot-busting drugs and over 94% on beta blockers. The program's success is due to its multi-faceted approach, including care standards, educational materials, reminders, and patient empowerment.
Patients in managed-care plans were less likely to receive coronary angiography following a heart attack compared to those with traditional fee-for-service coverage. This procedure is highly recommended for improving treatment options and reducing the risk of a second heart attack.
Researchers at Duke University Medical Center found that artificially intensifying the heart's pumping action, known as aortic counterpulsation, showed modest but significant benefits for the sickest heart attack patients. The technique, combined with clot-busting drugs, reduced six-month mortality rates by 4% compared to treatment alone.
A study by American Heart Association finds that consuming heavy meals may trigger heart attacks, increasing risk by about four times within two hours. The research suggests that eating a large meal can lead to temporary rises in blood pressure and heart rate, potentially causing heart attacks or strokes.
A study by Wake Forest University Baptist Medical Center found that heart attack survivors experience blood vessel disease progression three to four times faster than those without heart disease. Low levels of high-density lipoprotein (HDL) cholesterol and smoking history significantly accelerate this process.
A new study found that premenopausal women are more vulnerable to sudden, serious heart disease during their menstrual cycle when estrogen levels are at their lowest. The research also identified other health risks that worsen the odds for heart disease in young women.
A study of nearly three million fitness club members found a small but definite increase in risk of exercise-related fatal heart attacks or strokes among sporadic exercisers. Regular exercise is recommended to lower this risk, particularly for those with cardiovascular disease.
Researchers used MRI to show that statin drugs remove fat from atherosclerotic lesions, reducing the risk of heart attacks and strokes. Statins may detect patients at risk for cardiovascular disease, identify treatment options, and monitor treatment effectiveness.
A Mediterranean-style diet rich in olive oil, fruit, and fish was associated with a lower risk of death after a heart attack. The study found that participants who consumed more fresh fruits and vegetables had a reduced risk of dying within 42 months after their heart attack.
Researchers found that patients with periodontal disease had significantly higher levels of C-reactive protein in their blood than those without gum disease, indicating an increased risk of future heart attacks. The study suggests that treating severe gum disease may help reduce CRP levels and the risk of another heart attack.
Researchers found that children with a parent who had a premature heart attack showed structural and functional abnormalities in their arteries as young as 6 years old. These changes included thickened vessel walls and decreased reactivity, which can lead to atherosclerosis and increase the risk of heart disease.
A study of over 300 heart attack survivors found that only one in four called for help within an hour, while 12% delayed more than 24 hours. Prompt treatment can halve the risk of death from a heart attack, highlighting the importance of swift medical attention.
A community education study increased ambulance use among heart attack patients but showed no improvement in delay time. The REACT study found a 20% increase in emergency medical services usage without a corresponding decrease in Emergency Department visits.

The research, which monitored 14 young adults after they received a dose of cocaine, showed that even occasional use can have significant effects on cardiovascular health.
Researchers found calcified plaque in 7.5% of participants, doubling risk of death from cardiovascular disease compared to those without plaque. This discovery moves towards using panoramic dental radiographs as a screening tool for all cardiovascular disease.
A new study found that smokers carrying the gene GSTT1 face almost twice the risk of heart problems as non-smokers. The study analyzed data from over 14,000 participants and found that individuals without the gene had a 60% greater risk of heart problems if they smoked.
A new study found that hospital distress, particularly depression and anxiety, can predict poor heart attack outcomes and quality of life. Distressed patients reported more chest pain, poorer overall well-being, and increased healthcare usage.
Researchers at Duke University Medical Center found that almost 60% of patients with low-risk heart attacks do not experience complications beyond three days. While shorter stays may save resources, the study suggests that the additional day is often unnecessary and costs hundreds of millions of dollars annually.
Young women in Scotland are four times more likely to have a heart attack than those in the South of England, but survive at almost twice the rate. Ambulance response time may play a significant role in differences in mortality rates across UK regions.
The trial found that eptifibatide significantly reduced deaths and heart attacks by 40% within the first 48 hours of use. This represents a substantial improvement over the current standard treatment, abciximab, which costs $1,500 compared to $400 for eptifibatide.
Researchers found that aggressive treatment strategies, such as re-administration of clot-busters and emergency revascularization procedures, can reduce mortality rates almost threefold. However, many patients continue to receive conservative therapy despite these newer therapies being available.
